Low Drum Level in Boiler Operation – How to Handle

Low drum level operation leads to availability loss of the boiler. Water wall tubes fail due to short term overheating. Never bye-pass the very low drum level trip in boiler is to be adopted. The boiler availability loss due to a low drum level operation can be a major concern in power plants, hence it is always better to take preventives.
